Preparing the Workpieces

Before laying out the dovetails, prepare your wood pieces. Ensure they are cut to the required dimensions and planed smooth. This preparation aids in achieving precise measurements and clean cuts.

  1. Select the Wood: Choose hardwood for durability and aesthetic appeal.
  2. Cut to Size: Ensure both pieces (the pin board and tail board) are cut to the correct dimensions.
  3. Joint Edges: Joint the edges where the boards will meet to ensure a tight fit.

Marking the Dovetails

The marking process is critical for accurate dovetail joints. Follow these steps to mark both tails and pins:

For Tails:

  • Place the pin board flat on a work surface.
  • Use a marking gauge to establish the thickness of the tails.
  • Mark a line across the end grain to indicate the tail depth.
  • Decide on the angle of the tails (typically 1:8 or 1:6) and mark the layout using a square.

For Pins:

  • Transfer the tail profile to the end of the pin board using the marked tail board as a template.
  • Use a marking knife for precision, ensuring the lines are sharp and clear.

Cutting the Dovetails

With markings in place, proceed to cut the dovetails. Follow these detailed steps:

  1. Cut the Tails:
  • Start with the tail cuts using a dovetail saw. Cut along the marked lines.
  • Remove waste material with chisels, working from the edges towards the center.
  • Ensure that cuts are vertical and clean for a tight fit.
  1. Cut the Pins:
  • Position the pin board vertically and align it with the tail board.
  • Mark the pin layout based on the tail profile.
  • Cut the pins similarly, ensuring that the cuts are clean and precise.
Joint Type Tail Angle Typical Use
